(54) ENDOSCOPIC CAP, ENDOSCOPIC TREATMENT TOOL, AND ENDOSCOPE SYSTEM


(57) Provided is an endoscope cap (1) including: a cylindrical hood portion (2) that is attached to an outer circumferential surface of a distal end portion of an endoscope (10); a cap portion (3) that protrudes from a distal end of the hood portion (2) in a longitudinal direction of the hood portion (2), and that has an abutting surface (6) against which a distal end (10a) of the endoscope (10) is abutted in a state in which the distal end portion of the endoscope (10) is inserted into the hood portion (2); a channel tube (4) a distal end portion of which is fixed to a proximal end portion of the hood portion (2), and that extends substantially parallel to the hood portion (2); and a linear coupling member (5) that is supported by the hood portion (2), and that is for coupling a device (30) inside the tube (4) with the hood portion (2), wherein the hood portion (2) has a pair of support holes (7) that are separated from each other in a circumferential direction of the hood portion (2), that are formed at positions closer to the proximal end than the abutting surface (6) is and also closer to the distal end than a distal end of the channel tube (4), and into which the coupling member (5) is inserted, and the coupling member (5) can be pivoted with the individual support holes (7) serving as fulcrums.
